    Wide CompatibilityIt's not just a solar powered battery charger, it's an advanced solar battery maintainer for 12-volt sealed lead-acid car, automotive, marine, RV, power sport, boat, dump trailer, motorcycle, trolling motor, tractor, ATV and deep-cycle batteries, including flooded, gel, AGM, SLA and maintenance-free, plus lifepo4 lithium batteries
    Product Description

    As we all know, batteries naturally drain power and if allowed to go flat, may never regain their full power. This product is a solar powered battery maintainer and charger for 12V batteries and helps manage battery drain in all season. The solar charger converts light energy from the sun into 12 volt DC electricity which is then transported to the rechargeable batteries through lead wire and connector of choice, replace the self-discharge of a battery in storage, so that the battery wouldn't "go dead". It can be used for cars, 4WDs, trucks, motorcycle, marine, boats, farm equipment or any application where a 12V battery is used.

    The high efficient solar panel allows to absorb a wider spectrum of the sun light, as long as there is sufficient sunlight available, the charger will generate an electrical current to trickle charge battery. The charger is built in the most super ligent MPPT (Maximum Power Power Tracking) chip to ligently charge and fully protect battery. The MPPT technology helps to generates at least 20%-30% more power than traditional PWM. And the LED indicator helps better understand the charging statue in all days.

    Visual LED Indicator

    The led indicator allow to clearly monitor working status:

    Blink Green: Sunshine is effective (Not Acitve yet)

    Blink Red: Working to charge battery (Activated)

    Solid Green: Battery is fully charged

    Solid Red: Error-Reversed polarity
